LUBRICATOR Application filed August 24, 1923. Serial No. 659,145.

My invention relates to lubricators such as may be used in railway car and locomotive journal and driving boxes and consists in novel pump operating mechanism. In Patents Nos. 1,412,740 and 1,412,741 previously issued to me, I describe lubricators of the same general type in which a pump is operated by a reciprocating contact rod connected to the pump plunger by a bell crank lever and moved 1c in opposite directions by the alternate thrust of a collar or the like upon the journal and by a spring which is compressed by such j ournal movement and which returns the rod to its original position when the journal returns to its original position.

The objects of my present invention are to provide means for operating the pump independently oi": the movement of the journal movement for a portion of its cycle while still 1" utilizing the shifting to and fro ot the journal for the motive power of the pump.

In. the accompanying drawings which illustrate a selected modification of my invention,

Figure 1 is vertical, longitudinal section thru a locomotive driving box and the journal upon which it is mounted and illustrating the pump and pump operating mechanism in connection therewith.

Figure 2 is a vertical, transverse section so taken through the plunger.

The driving box is indicated at 1 and the body of the lubricator at 2. The driving box serves as a lubricant reservoir and. the lubricator body has an intake passage 3 in its lower portion and a discharge passage 4 in its upper portion. Intermediate these passages are flop and check valves 5 and 6 respectively which cooperate with the pump plunger 7 in feed ing the lubricant to the journal A.

The lubricator body 2 has a vertical cylinder surrounding the plunger 7 and the latter extends above this cylinder into a mechanism housing 8 where it terminates in an enlarged head. 9 provided with slot 10, the major axis of which is horizontal. Journaled upon the wall of housing 8 is a wheel or disc 11 havin a ratchet periphery 12, an eccentrically dis-- posed weight 13 and an eccentrically disposed pin 14 which extends into plunger slot 10.

A horizontal rod 15 is slidably journaled in the walls othousing 8 and extends outwardly ot' the lubricator and the driving box into a position where it is adapted to contact with a collar or other annular surface on the journal A. This collar, indicated at 16, may be the hub of a wheel mounted upon the journal. The outer end of rod 15 is enlarged at 17 to provide a seat for one end of a spring 18 which is compressed thereby against the outer face of the driving box and returns the rod to the right whenever the journal moves to that direption following a shifting movement to the let. I y

A pawl 19 is pivotally mounted upon rod 15 so as to aline with and engage the ratchet periphery of wheel 11. Obviously movement of collar 16 and rod 15 to the'lett will rotate member 11 the distance of. one or more notches according to the extent of the movement and the pitch of the teeth. Such movements re- 'ieated often enough will raise and lower the plunger and force the lubricant into the lubricator and out again into contact with the journal.

I WVhen the rotation of wheel 11 brings weight 18 to the uppermost position the weightoverbalances the wheel so as to cause the latter to turn the next 180 degrees independently of rod 15 and pawl 19 and somewhatfaster than is likely to result from'the pawl actuated movement. This portion of the movement of the wheel may be provided atany desired point, i. e. either on the upstroke or downstroke of the punger or half and half if so wanted. A detent pawl 20 may be provided for positively checking undesirable reverse movement of ratchet wheel 11.

It will be noted that the lubricator is spring supported in the driving box and that its top face is adapted to contain waste so as to more evenly and constantly supply the journal with lubricant. These features are common to the lubricators of this type and form no part of my present invention. It is obvious that the arrangement of the plunger, ratchet and operating rod may be varied in detail without departing from the spirit of my 1nvention and I contemplate such modifications as fall within the scope of the appended claims.

I claim:

1. In a journal lubricator, a lubricant pump, means for operating said pump thruout a portion of its cycle by relative movement of the journal to which it is applied and gravity actuated means for operating said pump thruout the remainder of its cycle.

2. In a journal lubricator, a pump, a rotatable pump-operating member to be turned continuously in one direction, means for tating said member by movement of the ournal lengthwise and relative to said member, and additional means for actuating said member during a predetermined portion of its rotation.

3. In a journal lubricator a body, a pump including a vertically reciprocating plunger having a horizontally extending slot at its upper end, an eccentrically weighted ratchet wheel having a pin engagement with said slot, a rod'slidably mounted in said body so as to parallel the axis of the journal, to which the lubricator is applied, with one end extending beyond said body to engage a collar or like annular surface on the journal, and a pawl pivoted on said rod and engaging said ratchet.

4. In a journal lubricator, a body including a pump cylinder, a plunger in said cylinder provided with a transverse slot in its outer end, a ratchet wheel having a crank pin engaging said slot, a rod slidably mounted in said body and extending outwardly thereof to contact with a projection upon the journal to which the lubricator is to be applied, a pawl pivoted on said rod with its tooth in engagement with said ratchet wheel, and a weight eccentrically carried by said wheel so as to accelerate the movement of said wheel independently of said ratchet and at predetermined points in the rotation of said wheel.

5.In a lubricator for a railway journal box, a pump including a reciprocal plunger, a vertically disposed rotatable member for operating said plunger, a weight on said member at one side of its axis, a reciprocal element for engaging the journal to be lubricated, and a pawl and ratchetconnection between said element and said member for moving the latter through that portion of its rotation when said weight is being lifted.

In testimony whereof I hereunto aflix my signature this 26th day of July, 1923.
